When I read queries in which the poster says: I bought X and I have no idea what it is or how to use it or what to do with it." I always think, that's weird, why would anyone buy anything if they don't know what it is or how to cook with it?
However, I revently did just the same thing. I saw this jar of red pasty stuff labeled Avjar. Only the ingredients are in English on a special label, but the rest of the label seem to be in an Eastern European/Balkan language. According to the label, It mostly contains roasted red peppers and vegetables. It tastes pretty good and is not vinegary. I read the wiki about it and it seems to be a Balkan chile pepper vegetable preserve.
So far I have stirred the avjar paste into two different types of soup to make the soup roasted red pepper flavored.
What else can I use this for? What are it's traditional uses?
Check your spelling - I believe it's ajvar, pronounced "eye-vahr", and if you Google it, there's lots of sites to see. I like to spread it on bread, with a turkey sandwich, instead of mayo.
Its terrific as a spread on bread with some cheese, esp sheep. YOu can cook it with scrambled eggs.
My SIL is from Sarajevo, and she eats a ton of this. We spreads it on pita, with olives, feta, and hot chillies on the side. It's addictive! If your brand was only "pretty good," then try others, because it varies greatly. The best ones taste heavenly!
In Romania, it's mostly eaten as a spread on bread. I have some in the fridge now. It's my husband's fast food. Ha!
